Erm..neither AC... tho I've not been 100% healthwise now you mention it..just wrapped up cos it's parkie and I was hanging around outside...
The Penfield jacket isn't one of these big padded things..it's a lightweight waterproof sorta thing hence my layers Sir..

Had a birthday bash last night at three different venues with on the expat socialites in here in the Hague:
The green Harry Stedman OCBD with flap
Rooster tie in green, blue and grey stripes
Buzz Ricksons officer pinks
Alden Longwings No.8
And grey herringbone J. Keydge

Early on in the evening I was accosted by a fabric designer based in London, who was intrigued by the texture and lines of my clothing and said she could tell I was a very interestng person and was I the person who organised the North Sea Jazz Festival? Which was one of those Paul Simon "Who I'm I to blow against the wind?" moments, and this did provide evidence that my intent in my style is being projected.

I was actually quite chuffed.

Damn them if they dont cater for us bigger boned ivyists.
One thing JS said to me the other day  " dont worry we will always have plenty of things in your size.
Reasuring that (my god i sound like Jim).

I'd say those patterns work fine.  Nothing clashing about it.  The tattersall is subtle enough and the check in the jacket's subtle enough. I would.
